checkIntegrityDo
void checkIntegrityDo() throws MalformedTreeException(Code)



checkIntegrityUndo
void checkIntegrityUndo()(Code)



considerEdit
protected boolean considerEdit(TextEdit edit)(Code)



createSourceComputationProcessor
static TextEditProcessor createSourceComputationProcessor(IDocument document, TextEdit root, int style)(Code)
